"It took a long time, but without the technology we would have never known," Houston admitted.

Patricia Lasserre was last seen leaving her job at the Clanton Walmart on December 19, 2005. She never made it to her Prattville home. Her SUV was found on Autauga County Road 1 and her body was discovered nearby.

Wynn's conviction comes within a week and a day of the seventh anniversary of Lasserre's murder.

Wynn, convicted of murder and rape in the first degree, will have a sentencing hearing on February 25, 2013. Houston's office says it will ask for the maximum life sentence.
